Members

ckid

Chunk identifier.

cksize

Size, in bytes, of the data member of the chunk. The size of the data member
does not include the 4-byte chunk identifier, the 4-byte chunk size, or the
optional pad byte at the end of the data member.

fccType

Form type for "RIFF" chunks or the list type for "LIST" chunks.

dwDataOffset

File offset of the beginning of the chunk's data member, relative to the
beginning of the file.

dwFlags

Flags specifying additional information about the chunk. It can be zero or the
following flag:

MMIO_DIRTY

The length of the chunk might have changed and should be updated by the mmioAscend function. This flag is set when a chunk is created by using the mmioCreateChunkfunction.
